To the Editor:The Joint Bank/Fund Health Services Department (HSD) in Washington, DC, was recently contacted with several requests regarding water temperature in the Bank’s restrooms. Because of the approaching cold/flu season, the staff was concerned that lukewarm water did not provide efficient ha 
The Environmental Cost of Misinformation: Why the Recommendation to Use Elevated Temperatures for Handwashing is Problematic.
TLDR
Health and consumer protection organizations should consider advocating for the use of a "comfortable" temperature rather than warm or hot water, and update beliefs about water temperature to prevent carbon dioxide equivalent emissions from many industrial sources in the U.S. including the Lead and Zinc industries.
Hand hygiene with hand sanitizer versus handwashing: what are the planetary health consequences?
TLDR
A comparative life cycle assessment was carried out to compare the environmental impact of the UK population practising increased levels of hand hygiene during the COVID-19 pandemic for 1 year and found that using isopropanol based hand sanitizer is better for planetary health.

Water temperature as a factor in handwashing efficacy
TLDR
Results of this first study indicated that water temperature exhibits no effect on transient or resident bacterial reduction during normal handwashing with bland soap, and the follow-up study examined the efficacy and skin irritation potential involving water temperatures with antimicrobial soaps.
Handwashing Water Temperature Effects on the Reduction of Resident and Transient (Serratia marcescens) Flora when Using Bland Soap
TLDR
Water temperature has no effect on transient or resident bacterial reduction during normal handwashing when bland soap is used, and this study evaluates the bacterial reduction efficacy of water temperature duringnormal handwashing.
How irritant is water? An overview
TLDR
Repeated water exposure without occlusion caused an increase in blood flow on irritated skin; however, clinical evaluation did not show a difference in dryness or scaling; much remains to be done to clarify the risk factors and mechanisms of water‐induced irritation.
